Still, what is the benefit of driving a company into bankruptcy while the actual responsible have left with a golden parachute? The only thing that works is to go after all responsible managers. The Sabanes-Oxley act was a start, perhaps it needs to be extended. And I do like the idea of rather forcing the company to invest in making up for their wrongdoing than plain fines which vanish in some budget.
The only trouble there is that what if a company wants to (for instance) invest in EVs anyway? Now the incentive is to first make a quick buck cheating and lying, and then when they get caught the punishment is to do the same thing they were planning to eventually do anyway.
